ACPI: APEI: EINJ: Fix EINJV2 initialization and injection
ACPI 6.6 specification for EINJV2 appends an extra structure to
the end of the existing struct set_error_type_with_address.
Several issues showed up in testing.
1) Initialization was broken by an earlier fix [1] since is_v2 is only
set while performing an injection, not during initialization.
2) A buggy BIOS provided invalid "revision" and "length" for the
extension structure. Add several sanity checks.
3) When injecting legacy error types on an EINJV2 capable system,
don't copy the component arrays.
Fixes: 6c7058514991 ("ACPI: APEI: EINJ: Check if user asked for EINJV2 injection") # [1]
Fixes: b47610296d17 ("ACPI: APEI: EINJ: Enable EINJv2 error injections")
